In this study, prediction errors resulted from periodic changes in the task, and DA recordings were made from the onset of training, thus back-propagation-like activity is directly apparent, although this activity was not quantified.
Their absence— along with increasing sea surface temperatures, rising sea levels (as glacial meltwater flowed into the world's oceans), and especially changes in the radiation budget of Earth's surface owing to Milankovitch variations (changes in the seasons resulting from periodic adjustments of Earth's orbit around the Sun)—affected atmospheric circulation.
The membrane retractions resulting from periodic contractions were at or below the limit of resolution of the light microscope and were observed as periodic decreases in the speed of protrusion, different from the other, large scale retractions observed.
This phenomenon has been called vasomotion and is due to changes in lumen diameters which result from periodic activity of muscle cells in the microvessel wall governed by oscillation of intracellular calcium concentration [ 46].
Therefore, Tau sequences are unlikely resulted from periodic firing of entorhinal grid cells.
Annual influenza epidemic and periodic pandemic outbreaks result from continuous antigenic changes within HA and NA proteins, known as antigenic drift and shift.
Seasonal colour changes result from hormonal changes associated with reproduction.
On the SAXS pattern representing the scattering from the non-deformed semicrystalline polymer, only one maximum of intensity, resulting from the crystalline periodic structure, is usually visible.
The background of scattering, resulting from the crystalline periodic structure, was subtracted, assuming its shape to be similar to that of the non-deformed sample.
Again, we observed that p300 bound to the enhancer in a periodic fashion, while Arnt bound to the DNA stably and persistently (Fig. 2C), indicating that the periodic fashion of p300 recruitment does not result from a periodic association of the HIF-2α/Arnt transcription factor with the enhancer of the gene.
Mr. McMahon also criticizes the extent to which New York relies on its wealthiest citizens for most of its revenue because of the potential volatility resulting from Wall Street's periodic crashes.
